They’re full of all your favorite pizza toppings and baked until tender and juicy! These meat and cheese stuffed tomatoes are hearty enough to be a meal — serve them with a salad for a low carb Italian inspired feast! And with only 4g net carbs, they won’t “eat” up your daily carbohydrate allowance!

Are Tomatoes Keto?

Tomatoes are a great option for low carb dieters, as the average medium-large tomato contains about 5g total carbs. Plus, the nutritional content of tomatoes makes them worth taking a few carbs of your daily allowance. Tomatoes are a good source of vitamins A, C, and E. They also contain lycopene, which may help prevent certain diseases.

I’m all about balance, which is why I make sure to incorporate vegetables and fruits (tomatoes are technically a fruit) at every meal. One thing to keep in mind about this particular recipe is that we are hulling out the tomatoes, so the carb count is actually lower than that of a whole tomato.

What You Need to Make Stuffed Tomatoes Keto

  • Beefsteak tomatoes — Top sliced off and middle removed
  • Pepperoni — finely diced
  • Red onion — finely diced
  • Shredded Mozarella cheese — I recommend slicing your own, if possible. Store-bought shredded cheese often contains starches and fillers to prevent clumping.

Spice Mix

  • Basil
  • Oregano
  • Stevia powder (optional)
  • Coarsely ground black pepper
  • Salt

Kitchen Tools Used

  • Muffin tin or baking dish

How to Make Keto Stuffed Tomatoes

First, preheat your broiler (on high) and prep your ingredients. Chop the onions and pepperoni, shred cheese, etc. Whisk together your spice ingredients in a small bowl and set aside.

Wash your tomatoes and slice of the top (about 1/2″ or so). Use a paring knife to cut away the seeds and juicy inner flesh of the tomatoes. You can also use a spoon to scoop out the middle.

Fill the middle of each tomato with a layer of onion, pepperoni, spice mixture, and cheese. Gently use your fingers to press down the filling and repeat the layers. You want the tomatoes to be slightly overfilled, as the filling will shrink down a tad when the cheese melts.
